It integrates an internal voltage reference and communicates over SPI or parallel data bus. The through-hole 24-pin DIP package (0.300\" body width) makes this ADC a natural fit for socketed prototype boards, MRO replacement in existing equipment, or designs where vibration resistance isn't the primary concern. Operating temperature is rated 0°C to 70°C, so it belongs in controlled indoor environments — lab instrumentation, benchtop test gear, industrial control cabinets with climate management, or commercial data-acquisition front ends. ## Supply rails and signal chain planning The analog section runs on ±5V bipolar supplies or a single 5V rail, while the digital interface requires a separate 5V supply. That dual-supply architecture means your board needs a clean ±5V analog rail — a switching supply followed by a low-noise LDO or a post-regulator filter stage. The pseudo-differential input accepts a signal referenced to a common-mode point, which helps reject ground noise between the sensor and the ADC when the source is remote. ## Lifecycle and sourcing — still an active line The MAX191BCNG+ carries an Active product status with ROHS3 compliance. The through-hole DIP package is a mature, non-moisture-sensitive format; store the tubes in a standard ESD-safe cabinet, no dry-bake required before reflow (though reflow doesn't apply here — hand-solder or wave-solder only).","metaTitle":"MAX191BCNG+ 12-Bit SAR ADC, 100k SPS, 24-PDIP","metaDescription":"Maxim Integrated MAX191BCNG+ 12-bit SAR ADC, 100k samples/sec, pseudo-differential input, internal reference, SPI/Parallel interface, 24-PDIP.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":"ROHS3 Compliant","productStatus":"Active","categoryPath":["DC-DC Power Modules"],"specifications":{"Package":"Tube","Input Type":"Pseudo-Differential","Architecture":"SAR","Configuration":"S/H-ADC","Mounting Type":"Through Hole","Data Interface":"SPI, Parallel","Number of Bits":"12","Package / Case":"24-DIP (0.300\\\", 7.62mm)","Reference Type":"Internal","Ratio - S/H:ADC":"1:1","lifecycle_stage":"eol_hot","Number of Inputs":"1","Operating Temperature":"0°C ~ 70°C","Supplier Device Package":"24-PDIP","Number of A/D Converters":"1","Voltage - Supply, Analog":"±5V, 5V","Voltage - Supply, Digital":"5V","Sampling Rate (Per Second)":"100k"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$33.06","stockQuantity":0,"priceTiers":[{"qty":1,"price":"$33.06000","currency":"USD"},{"qty":10,"price":"$30.49100","currency":"USD"},{"qty":25,"price":"$29.12040","currency":"USD"},{"qty":100,"price":"$26.03700","currency":"USD"},{"qty":250,"price":"$24.83792","currency":"USD"}]},"links":{"datasheetUrl":"https://datasheets.maximintegrated.com/en/ds/MAX191.pdf","sourceUrl":null},"ai":{"faq":[{"question":"How many bits does the MAX191BCNG+ have?","answer":"The MAX191BCNG+ is a 12-bit ADC, providing 4096 discrete output codes over its input range."},{"question":"Does the MAX191BCNG+ have an internal reference?","answer":"Yes, the MAX191BCNG+ includes an internal voltage reference, eliminating the need for an external reference IC in most applications."},{"question":"What is the input type on the MAX191BCNG+?","answer":"The MAX191BCNG+ has a single pseudo-differential input channel, which accepts a signal referenced to a common-mode voltage for improved noise rejection."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/analog-devices/MAX191BCNG","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/analog-devices/MAX191BCNG when reusing this data.
